18 Year old inelligible to book cruise out of Singapore?

[Ethanol95]

So I've been reading up on the minimum age requirements one has to be in order to cruise without an older adult. The sailing that I am looking at specifically is the 4 night roundtrip from Singapore on 13th Nov. 2015. On the guidelines it says that cruises originating from South America, Europe, ASIA, Australia and New Zealand allow 18 year olds to sail unaccompanied. However, does this mean that I (meaning an 18-year old), cannot book online? Does it not take into account different laws when booking online?

 

I tried booking and it said at least one traveller has to be over the age of 21 or accompanied by an adult over the age of 21. But we are departing from Singapore where 18-year olds can legally travel by themselves.

Thanks very much in advance.

Why don't you call them and ask if you can book it.
